Professor Anette "Peko" Hosoi, graduate student Brian Chan and junior Catherine Koveal demonstrate RoboSnails I (right) and II. RoboSnail I has since been rebuilt to be the same size as the smaller RoboSnail II.

Basic research on complex sugars has led to a cascade of potential medical applications that could, for example, significantly improve outcomes for patients undergoing major operations such as heart bypass surgery and impact a multibillion dollar drug industry.

Not only does the Y chromosome contain far more genes than scientists thought; it also includes a large number of genes arranged in ways that may allow the Y to mimic the paired chromosome structure of the rest of the genome.

An MIT interdepartmental laboratory has received $7.2 million from the NIH to further its work on devices that can detect and image precancerous cells as noninvasively as shining a tiny beam of light onto a patient's tissue.

By discovering one of the first mechanisms through which brain synapses are dismantled, Morgan Sheng has taken a step that may lead to the prevention or minimization of synapse loss associated with neurodegenerative diseases such as Alzheimer's.

In a finding that may help create unlimited quantities of therapeutically valuable adult stem cells, James Sherley has found a way to treat adult rat liver stem cells so they multiply like embryonic stem cells, and can also revert to acting like normal adult stem cells.

In a step that might help explain the mystery of how high-temperature electrical superconductors work, three research groups have observed molecules form a collective identity at ultracold temperatures.
